Every aspect of the Chesterton 280M design is optimized for high reliability in demanding conditions. This motion-tolerant dual seal:
- Withstands run-out and end-play common to mixers, double-ended or vertical turbine pumps, and other rotating equipment
- Delivers instant pressure-shift capability that eliminates worries under jarring purge and reverse pressure cycles
- Has vibration-isolated faces which thrive under conditions of drag and shear that destroy common seals
- Designed with internal cooling that results in stable, long-life sealing
